picom-trans - an opacity setter tool

picom-trans [-w WINDOW_ID] [-n WINDOW_NAME] [-c] [-s] OPACITY

picom-trans is a bash script that sets _NET_WM_WINDOW_OPACITY attribute of a window using standard X11 command-line utilities, including xprop(1) and xwininfo(1). It is similar to transset(1) or transset-df(1).

-w, --window=WINDOW_ID

Specify the window id of the target window.

-n, --name=WINDOW_NAME

Specify and try to match a window name.

-c, --current

Specify the currently active window as target. Only works if EWMH '_NET_ACTIVE_WINDOW' property exists on root window.

-s, --select

Select target window with mouse cursor. This is the default if no window has been specified.

-o, --opacity=OPACITY

Specify the new opacity value for the window. This value can be anywhere from 1-100. If it is prefixed with a plus or minus (+/-), this will increment or decrement from the target window’s current opacity instead.

-g, --get

Print the target window’s opacity instead of setting it.

-d, --delete

Delete opacity of the target window instead of setting it.

Toggle the target window’s opacity: Set opacity if not already set, and delete if already set.
